1. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

2. A client with chronic kidney disease needs dietary restrictions. What restriction is necessary?

• A. Increase protein intake
• B. Limit potassium-rich foods
• C. Increase fluid intake to prevent dehydration
• D. Increase phosphorus intake

Correct answer: B

Rationale: The correct answer is to limit potassium-rich foods for clients with chronic kidney disease. Excessive potassium can be harmful to individuals with compromised kidney function, leading to complications. This restriction helps in managing the condition and preventing further health issues. Choice A is incorrect because increasing protein intake can put additional stress on the kidneys. Choice C is incorrect as excessive fluid intake can burden the kidneys. Choice D is incorrect as increasing phosphorus intake can be harmful for individuals with kidney disease.

3. A client is being taught about taking warfarin to treat atrial fibrillation. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will take this medication on an empty stomach.
• B. If I forget to take a dose, I can take it later on the same day.
• C. I will skip my dose if I forget to take it.
• D. I can take an additional dose if I miss one.

Correct answer: B

Rationale: The correct answer is B because taking warfarin later on the same day if a dose is missed helps maintain therapeutic levels. Choice A is incorrect because warfarin should be taken with food to enhance absorption. Choice C is incorrect as skipping a dose can lead to fluctuations in warfarin levels. Choice D is incorrect as taking an additional dose can increase the risk of bleeding.

4. A nurse is reinforcing teaching about wound care for a client who has a wound requiring irrigation. What is an important instruction?

• A. Wear sterile gloves when applying a new dressing
• B. Cleanse the wound from the center outwards
• C. Keep the wound dry between dressing changes
• D. Apply an antimicrobial ointment to the wound

Correct answer: B

Rationale: The correct answer is to cleanse the wound from the center outwards. This technique helps reduce the risk of contamination by pushing debris away from the wound. Option A, wearing sterile gloves, is important for infection control but not specifically related to wound irrigation. Option C, keeping the wound dry, is not suitable for wound irrigation, which often involves using solutions to clean the wound. Option D, applying an antimicrobial ointment, is not typically done during wound irrigation as the focus is on cleansing the wound.

5. How should a healthcare professional assess a patient for potential deep vein thrombosis (DVT)?

• A. Assess for unilateral leg swelling
• B. Encourage early mobilization
• C. Check for calf tenderness
• D. Observe for redness and warmth

Correct answer: A

Rationale: To assess a patient for potential deep vein thrombosis (DVT), healthcare professionals should look for unilateral leg swelling. This is a classic sign of DVT. While encouraging early mobilization is generally beneficial for preventing DVT, it is not a method of assessment. Checking for calf tenderness is also relevant but not as specific as unilateral leg swelling. Observing for redness and warmth can be signs of inflammation but are not as specific to DVT as unilateral leg swelling.
